On July, a Japanese friend named Toshi and I decided to climb Kitadake, who is Japan's second highest mountain. Knowing this wouldn't be easy 1I started training. I went jogging and swimming regularly to trying and prepare and was feeling fit and ready at the end of July. At the beginning of August, the number of Corona cases was increasing so unfortunately we had to change our plans. Toshi doesn't want to catch the bus from Kofu to the Suothern Alps because of the risk of Corona infection, so we stayed in Shizuoka prefecture. Yanbushi was a mountain, 2014 meters high. It is not far from Umegashima, which is famous for it's hot springs. Instead of Kitadake, we climbed Yanbushi. In August 10, we woke up early and drove to the starting point. It was the day after a typhoon had passed and a beautifull, clear morning in Shizuoka city. However when we arrived, it was very cloudy and it was raining lightly. After a three and a half hour climb we arrived at the summit. It rained most of the way but it wasn't so bad under the trees and actually kept us cool. It was a challenging and rewarding experience. Ithink exploring nature is a fun, healthy and interesting way to spent your free time. T have included a photo of my climb.
